Network Locations using PowerShell

So you can’t manage your network locations from PowerShell by default.  Here is a great dll you can add to expose network locations.
Download and extract the dll into your scripts directory from http://archive.msdn.microsoft.com/NLM  Look in \NLMCSharp.zip\NLMCSharp\obj\Debug


Add-Type –Path .\Interop.NETWORKLIST.dll
$nlm = new-object NETWORKLIST.NetworkListManagerClass
$nlm.GetNetworks("NLM_ENUM_NETWORK_ALL") | select @{n="Name";e={$_.GetName()}},@{n="Category";e={$_.GetCategory()}},IsConnected,IsConnectedToInternet
